Cancel Service

In September last year I signed up with a fibre provider (not Telkom) and ported my phone number to that provider. In October I telephonically contacted Telkom and requested cancellation of the voice service and to keep my mailbox service active and was given the Ref No ***1 I was told it would take a month for this to take effect, this did not happen. Later in October I again contacted them and was told that the cancellation had not been done and they would do it now and was given a reference number, later on that same day I received an SMS stating that my details had been updated. At the beginning of November I received an SMS stating that the fault with the reference number I had been given was now resolved. Later in November I sent an Email to 10212 and cc to 10213 I received a reply to which there was an attachment stating that an IT ticket has been logged, to date I have had no communication with regards to this ticket. Since then I have tried to call 10210 a number of times with no successful conclusion. I then decided I would go to a Telkom shop to try and sort this out (this is very difficult for me as I am disabled and I needed to get a wheelchair and have someone take me there). I did this on 8 April and was told it would take effect on 9 May (Ref No ***3 given) unfortunately this also didn't happen. On the 14 May I again phoned 10210 and was told by the operator that the service had not been cancelled and when she tries to cancel the service the system refuses, she cannot explain why and all she could do is escalate the problem to the IT department again, and gave me Ref No *** I don't think will do any good as it has been escalated to IT before. I cannot just stop paying for this service as there is a debit order at the bank which has to be cancelled by Telkom I am therefore paying for a service I am not using since October last year. Please can you help to sort this out
